Egg prices have risen to levels not seen since late 2015 in some parts of the country, suggesting that supply is realigning with demand after a disease outbreak killed millions of U.S. chicken a couple of years ago.

Retailers, however, are resisting the industry's push by taking losses on eggs to draw customers.

Ken Shea, Bloomberg senior analyst of food and beverages, said retailers such as Wal-Mart and Aldi are willing to take a modest loss on some staples -- like milk and eggs -- if that means more people are going into the store to buy other items.

The U.S. Department of Agriculture reported last week that egg prices in U.S. stores have risen steadily over the past month to meet increased seasonal demand.
